BOTTLE.

Application filed March 6,

To all l107mm, 'it may concern a n Be it known that I, FRANK GADE, acitizen of the United States of America, and a resident of Fredsville,Grundy county, Iowa, have invented certain new and useful Ihmprovementsin Bottles, of which the following is a specication.

My invention relates to improvements 1n bottles, and the object of myimprovement is to supply a bottle or other receptacle with means forsuitably controlling its vent passage to permit the emptying of thecontents thereof after filling, but to prevent 'the successful refillingthereof after emptying. This object I have accomplished by the meansivhich are hereinafter described and claimed, and which are illustratedin the accompanying drawings, in Which:

Figure 1 is a central vertical section of a bottle equipped With myimproved means for preventing refilling thereof, and Fig. 2 1s ahorizontal section of such means taken on the line ah?) of said Fig. 1.

Similar numerals of reference denote corresponding parts throughout theseveral views.

rlhe bottle or jar 1 is shown as having a relatively large neck 2 forpurposes of convenient representation and description, but the neck maybe smaller or of different form and its passages inclined in other ivaysWithout departing from the principles of my invention.

The neck Q is integral with the body 1 of said bottle, and is providedWith a vent passage comprising the communicating chanw nels 3 and et ofWhich the channel l is at once the more contracted in diameter and ofless height, with its junction to the other channel preferably in theform of an annular downwardly concaved shelf to Whose curved contour thevalve 5 is conformed to fit it closely. The upper channel 3 iscylindrical throughout. An inclined cylindrical pit 13 extends into saidneck 2 from its upper surface, for a distance. The numerals^10 and 11denote two passages slightly inclined to the horizontal and which leadfrom the vent 3, in a slightly divergent Way to bend around the pit 13to communicate therewith just above its bottom and at its side nearestthe hither side of the neck, as best shown in Fig. 2.

The bottle may be filled through the open Specification of LettersPatent.

channels 3-4 in the usual manner. Then Patented Jan. 27, 1914.

1913. Serial No. 752,406.

the valve-body 5 is deposited in the channel 3 to rest tittingly uponthe concaved shelves thereof, which closes the channel 11 when thebottle is upright. The valve-body has a conveX lower face, and if it ispressed out of metal its upper face may be concave, and has integralupstanding marginal lugs G which contact with the inner Wall of thechannel 3, to keep the valve at a right angle to said Walls when movingback or forth in the channel and prevent its binding or overturning,which Would nullify the action of the closing means.

The bottle being filled, and the valve-body depositedv on its seat asshown in Fig. 1, the upper end of said channel 3 is permanently closedby a stopple 8, Which may be of glass or other suitable material. Theivall of said channel 4 as also the abutting part of said stopple 3 aresupplied With registering notches Which together form an opening or pit,and this pit may be filled With molten glass Which produces a key 9 inthe shape of an inverted Wedge to lock the stopple to said channel,preventing removal of the stopple Without breaking the Wedge and thebottle neck, thus destroying the usefulness ofY the bottle forrefilling. The stopple has an integral depending central projection 7Whose use will be hereinafter described, and Whose end is locatedapproximately opposite the center of each of the openings of thepassages 10 and 1l into the channel 3. Then the stopple has been thussecured, a metal cap 14 may be fitted over the neck with its edgecrimped over the terminal bead of the neck, or in lieu thereof a corkmay be placed in the pit 13.

To empty the content-s of the bottle, the latter is tilted or invertedenough to cause the valve-body 5 to move along the channel 3 under theinfiuence of gravity, to a position Where its upper flat surface willcontact With the stop-finger 7, this position of the valve beingindicated by dotted lines in Fig. 1. In the latter position, themarginal edge of the valve lies nearly medially across the openings ofthe passages 10 and 11 int-o the channel 3. The contents of the bottlemay then escape through said passages 10 and 11 and the pit-vent 13. Ifthe bottle be noW returned to its upright position, the valve 5 Willfall back to its first position to close the channel 4 and prevent thereiilling of the bottle. If the bottle is laid on its side or beinverted, the valve-body 5 will move toward the stop-linger 7 which willlimit it to the position shown, where its marginal edge will divide theinner openings of the channels l0 and l1 about evenly on both sides ofthe valve. If the attempt is made to inject a liquid through saidopenings, it will be seen that the inflowing stream will be divided bythe sharp margin of the valve so that a part will lill the small spacebetween the valve and the stopple 8, and that only an equal small amountof liquid can enter the channel 3 below the valve before the pressure onthe upper face of the valve will cause the valve to move toward itsseat, thus cutting oft' the openings of the passages 10 and ll from saidchannel. Since only a few drops of liquid may then enter the channel 3below the valve at a time, the attempt to refill the bottle becomesimpracticable, since in order to completely fill the bottle, it wouldhave to be restored to its first position and then inverted, very manytimes, while after a little liquid had entered the channel 4, it wouldact as a seal to inclose the air above it, and cause an increasingback-pressure from the confined air, which would prevent the bottlebeing filled.

Having described my invention, what l claim as new, and desire to secureby Letters Patent, is:

l. The combination with a bottle neck having a channel therein providingcommunication between the exterior and interior of the bottle, of asolid valve movable in said channel and limited in its travel in bothdirections, a stopper sealed into the outer end of said channel, saidneck having a conduit leading from said channel at a point below itsupper end to provide communication with the exterior of the neck, saidvalve being limited in its travel toward said stopper so that it willexpose a portion only of said conduit.

2. The combination with a glass bottleneck having a channeltherethrough, of a solid valve movable therein and limited in its travelto and fro, a glass stopple sealed into the outer end of said channel ata point spaced from the limit of travel of said valve in that direction,and a conduit being provided in said neck extending therethrough fromits exterior to communicate with said channel at a point in the latterwhere it may extend to opposite sides of said valve when the latter isat its limit of movement in one direction.

3. The combination with a glass bottleneck having a channel therein, ofa solid valve movable and fittingly seated in said channel and limitedin its travel therein in either direction, a glass seal in the outer endof said channel secured to its inner wall, and a conduit extending froma medial part of said port on one side to the exterior of the bottleneck, said conduit having its outer end set at an angle to the top ofthe neck and extending downwardly with a closed lower end, the otherpart of the conduit being divided into two parts both opening into saidfirst-mentioned channel and both opening into the first-mentioned partof the conduit at a point above its bottom and on the side farthest fromthe said first-mentioned channel.

4. The Combination with a glass bottleneck having a channel and avalve-seat therein with concave upper face, of a solid valve in saidchannel having a convex lower face adapted to fit said valve-seat andsaid valve being movable in said channel and having a plurality of smallspaced projections thereon lying along the wall of the port to keep italined therein, a glass body sealed into the outer end of said port toform a frangible stopple therefor and having a central dependingintegral linger onits lower surface adapted to limit the travel of saidvalve to space it therefrom, and a conduit extending from said port froma point spaced from its upper end and in communication with the exteriorof the neck, said conduit being bent in its course, and opening intosaid port partially above the upper limit of travel of said valve.
